UV222 Pass-Through Box
Efficient decontamination of smaller equipment

The UV222 Pass-Through Box offers microbial decontamination of smaller equipment in a rapid process that prepares the equipment for transfer between cleanroom areas without causing any material degradation or particle transfer.

Decontamination is key
when working in a cleanroom environment

When transferring to a higher-grade cleanroom, operators must follow strict protocols to minimise the bioburden in the cleanroom. This requirement also applies to smaller equipment such as cell phones, goggles, safety shoes, gloves, syringes, or bottles, and demands swift and efficient decontamination measures.

The UV222 Pass-Through Box provides an effective solution for rapid microbial decontamination. This device features a two-door system, which allows access from different cleanroom grade areas. The Pass-Through box ensures not only efficient decontamination, but also prevents the transfer of particles from one area to another.

Materials remain intact

The UV222 Pass-Through Box is gentle on materials, ensuring that they remain unharmed during the decontamination process, in contrast to decontamination using conventional UV-C light.

This guarantees that critical equipment remains intact and reliable for continued use in the cleanroom after being processed in the UV222 Pass-Through Box.

Installation and maintenance

The UV222 Pass-Through box is designed for easy installation and maintenance in various locations, depending on the requirement of the cleanroom. The surface is accessible for cleaning and can be ordered in one of two types of medical-grade stainless steel (304L or 316L), renowned for their strength, durability, and corrosion resistance.
